Abstract: A communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for internet of things (IoT) is provided. The communication method includes applying to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure relates to a method and an apparatus for allocating a phase tracking reference signal (PTRS) for estimating and compensating for phase distortion due to phase noise, Doppler effect, or synchronization error.

Abstract: A communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT) is disclosed. It may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A signal transmission and reception method implemented by a terminal of a mobile communication system is provided. The terminal receives first information including a request for beam related information from a base station and transmits second information including the beam related information based on the first information to the base station. The terminal changes at least one of a Tx beam or a Rx beam associated with the base station, based on the first information and the second information.

Abstract: The present disclosure relates to a fifth generation (5G) or pre-5G system to be provided to support a higher data transmission rate since fourth generation (4G) communication systems like long term evolution (LTE). A system and method for compensating phase noise of a terminal in support of the system is provided. The method includes measuring first channel state information (CSI) using a reference signal transmitted from a base station, estimating second CSI from the first CSI using a first type reference signal for compensating a common phase error (CPE) and a second type reference signal for compensating the CPE and inter carrier interference (ICI), and feeding back the estimated second CSI to the base station.

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). In a feedback method of a terminal, receiving a first subframe from a base station, detecting, from the first subframe, downlink control information (DCI) including transmission timing information and frequency resource information for feedback, creating feedback information for data decoding of the first subframe to be transmitted in a second subframe determined based on the DCI, and transmitting the feedback information, based on a time resource indicated from the transmission timing information and a frequency resource indicated from the frequency resource information in the DCI.
